Yellow tail acei holding?

first and foremost, sorry for no pics, i just noticed the fish last night before bed and havent had time to round up the camera. i will work on it when i get home from work today.

ive had my yellow tail acei for about a 10 months i think, they are all in the 2.5" - 3" range.

last night i noticed that one of the acei looked like it had a big rock stuck in its mouth. its mouth wouldnt close all the way and the sides of its mouth seem to be pushed out, as well as under the mouth. last night i couldnt get a good look, but this morning it was looking me right in the eyes so i had a perfect frontal view.

its mouth was slightly open and it looked like eggs were in its mouth, im not sure tho. it looked like little off-white balls.

does this sound like its holding eggs?

it does to me, but for some reason im concerned that maybe its something lodged in its mouth. not sure where my paranoia is coming from lol.

I have had two Acei. I guess a male and female because I have about 13 little fish. Not sure what to do with them. I had them in the same tank for about 2-3 weeks and they are getting bigger. What should I do with them? I only have a 40 gal tank.
